TYPE-WRITING AND SIMILAR MACHINE.

desired letters or characters into alinement with each other and thusform a complete line of the desired length or number of words ready forbeing impressed or printed 011 to the paper or other surface intended toreceive the impression.

According to this invention the various type or characterbearing wheelsare adapted to be successively displaced angularly about the spindle orshaft upon which they are mounted, the extent of the angular movementdepending upon the particular type or character thereon that is requiredto be brought into position at the printing point; the operating keysbeing arranged in such a manner as to regulate the degree of the angularmovement so as to correspond with such characters.

The type or character wheels are normally held against an gularorrotatory movement by means of suitable catches or equivalent devicesadapted for operation in such a manner that each type wheel may rotatein either direction, the said wheels being so balanced that in the eventof a catch being merely withdrawn from contact therewith, each typewheel will tend to rotate in the one direction. The said wheels mayhowever, be arranged so as to overbalance and so rotate in the otherdirection so that the degree of rotation and consequently the particularletter, figure, character, etc., is determined by means of stopsarranged to operate in a quadrant like member situated preferablybeneath and concentric with therow of type wheels. To'this end, theaforesaid stops are arranged in such a manner that, upon being operated,they are caused to come into contact with projections formed or providedon the type or character wheels. The type wheels are each arrangedopposite to and Specification of Letters Patent.

preferably above a quadrant shaped carrier for the stops so that thereare as many quadrants as there are type wheels.

There are a suitable number of universal bars extending the entirelength of the machine and each universal bar can be oper ated by twokeys.

Mounted with a capability ofintermittent transverse motion is atraveling lug or carriage containing a series of pins or stops having avertical displacement, the number of pins being equal to the number ofuniversal bars. This carriage travels and comes to rest under each typewheel in succession. As the carriage travels under the type wheels, thepins are displaced upwardly upon the depression of the keys, whereuponthe said pins come into contact with and force upward the stop in theaforementioned quadrant shaped carriers which are permanently under eachtype wheel, the said stops being retained in their upward position byfriction.

The pins in the traveling carriage are loose and return to their lowestposition immediately they have acted upon the stops.

Provision is made for returning the traveling carriage and type wheelsto their normal or zero position after printing by means of spring orlike devices and suitable means are arranged for justifying the spacingand correcting.

In order that the said invention may be clearly understood and readilycarried into effect, I will proceed to describe the same more fully withreference to the accompanying drawings in which Figure 1 is a sectionalelevation of a type writer embodying the features of my presentinvention. Fig. 2 is a sectional plan illustrating the arrangement ofthe keys and universal bars. Fig. 3 is a sectional plan in detail of thequadrant shaped carrier which constitutes the bed in which thevertically displaceable stops are mounted.

Fig. 15 is a detail view of mechanism for effecting theresetting of the type wheels. Fig. 16 is a view showing the hooked armswhereby the type wheels are retained in their normal position.

A indicates one of a series of type wheels having the requisite type orcharacters arranged upon its periphery; the said wheel is mounted withthe capability of rotating in either direction upon a boss or disk (4which is keyed to the shaft or spindle B (Fig. 1).

C C, E E represent one set of keys operating the rods 0 6 respectively.

F represents the traveling carriage carry ing the pins f; in the initialposition, the ends of these pins f rest respectively upon the universalbars P.

G is the quadrant shaped device whereby the stops 9 are carried. Thestops are preferably in the form shown in Fig. 3 so that when pushedupward by any of the pins 7 they are frictionally held in position inthe bed H. The friction may however be applied by a comb-like device 32(Figs. 3 and 3 mounted at the back of each row of stops in such a mannerthat each toot-h of the comb puts friction on the respective stop withwhich it is in contact.

J J are projections on the type wheels A, J being longer projectionsthan those inclicated at J.

K is the overbalancing weight which is mounted laterally with respect toa vertical line drawn through the axis of the wheel and L is a hookedarm pivoted at L, whereby the wheel is maintained in a position inreadiness for operation.

9' is a rod pivoted at the rear of the side frame. This rod 9' isnormally held up by a spring 2*. The front end of the rod comes over aprojection 3 formed on a lever i which is mounted on a spindle to whichis also attached a cylinder This cylinder has a. segmental strip cut outfrom it, lengthwise, and in the space thus formed projecting arms 5 onthe arms L enter.

6 is a projection on the rod 9 and on the downstroke of the lever 0 thisprojection pushes down the rod which turns the cylinder Q2 throughengaging with the lever i and the top face of the segmental opening inthe cylinder comes against the arms 5 and withdraws all the levers Lfrom engagement (to allow for the return of the traveling carriage), onthe upstroke the under face of the segmental opening comes in contactwith the other side of the arms 5 resetting all the lever catches Lready to hold the type wheels which are now settling after beingcollected by the collecting frame Y. The return movement of the cylinder9 is effected by means of a suitable spring which tends to keep saidcylinder in the normal position.

N is a printing roller which is adapted to carry the paper or the likein any convenient or well known manner, and which is operated so as tobe brought down upon the type by means of the lever O.

Q is the frame in which the parts are mounted.

Assuming the machine to be provided with two keys adapted to select andbring four type units into position the operation is as follows :Theaforesaid projections J J on the type wheel A are arranged pref erablyat equal intervals and are disposed so that a short projection appearsdiametrically opposite a long one. Upon the depression of a key lever,say, for instance that indicated at C, an angular motion is imparted tothe rod 0 thereby causing the universal bar P (Fig. 2) by means of thelink 0 to rise, in turn causing one of the pins to lift and push up oneof the stops 9. Upon releasing the key C pin f previously pushed upreturns to its normal position, but the stop 9 remains in its upwardposition. At the same time the traveling carriage F moves one step tothe right as will be hereinafter explained and in so doing theprojection L on the carriage comes into contact with the lower part L ofthe hooked arm L thereby causing the same to withdraw from engagementwith the type wheel and allow the latter to rotate due to the action ofthe weight K. The stop 9 is forced into such a position that it projectsinto the path of the projection J when the wheel rotates, so thatassuming the pin f to be pushed up so as to cause the stop 9" to enterthe path of the type wheel which normally rotates in the direction ofthe arrow, the said type wheel will go on rotating until the stop Jcomes into contact with the projected stop 9* whereby it will bearrested and be held in that position, a certain letter being therebybrought to the printing point. If the key C be pressed, however, thefact of it having a thicker washer atits lower extremity than the key Cwill resuit in a shorter stroke and said key will thus impart lessrotation to the rod 0 so that the stop g is not pushed up so far as inthe previous case, and the projection J* on the type wheel, when thelatter rotates, clears the stop 9*, and so the type wheel rotates untilit is arrested one of the projections J arriving in contact with theprojected stop 9*. It will be thus understood that half the keys operatewith a short stroke and half with a long stroke, so that each stop maybe thrown upward in two different positions. This movement in conjunction with the mechanism forreversing the direction of rotation ofthe wheel, gives to each stop the capability of selecting fourcharacters. The arrangement may also be such that other selections maybe obtained byyarying the number or lengths of the projections employed,and the movements imparted to the stops, the type wheel being adaptedfor movement inthe one or the other direction; or the wheel may beadapted to operate in one direction only. This may be effected byconstructing the projections on the type wheels of varying lengths, andby arranging the travel of the keys so as to give to the stops strokesof varying lengths corresponding to the varying lengths of theprojections on the type wheels. It will be understood that the releaseof a key causes the traveling carriage to move on one step and this iseffected by means of links f (Figs. 5 5 and f (Fig. 5 which areconnected to one end of the universal. bars and loosely mounted upon theshafts R R, Fig. 5. Keyed to each of the shafts R R is a strip of metal7, 7 along the whole length of which is fixed a strip of felt or othersoft material. hen the universal bars rise, the links 7" and f moveangularly about the shafts R, R and cause the strips of metal 7 f toimpart an angular motion to the said shafts R R. These shafts R R carrytoothed pinions R R which mesh with a toothed wheel R The angular motionof shafts R, R causes the twisted blade R keyed to the shaft R and setat an angle to its plane of motion, to impart a rocking movement to therack S by engaging with the corresponding blade It secured thereon.

In Fig. 4 the full line section of the rack S shows the latter in thenormal position, and the dotted section in a rocked over position, whichis the position chosen in Fig. 5. It will be observed that the rack Shas three rows of teeth, two beveled rows 8, 8

cut therein, and half a tooth in advance of each other and one row 8 outon the inner outside face. 2 is a hinged double pawl which can engagewit-h either row of inner teeth. When the inclined faced arms R and R(Fig. 5), hereinbefore described, cooperate, the rack S is rocked over,and the inner row 8 of teeth with which the pawl 2 is in engagement(Fig. 4 full lines) leaves this side of the pawl, and the pawl movesforward the distance of one tooth engaging with the inner row 8. Thismovement takes place just after the catch 5 has engaged with one of thespaces of the row of teeth 8 at the back of the rack (Fig. a dotted).Vhile the rack is resuming its normal position the pawl 2* leaves theinner row sand engages with one of the teeth of the row 8 one tooth inadvance. Just before the rack has resumed its normal position the catfih5 comes out of engagement with the teeth 8 at the back of the rack Sthereby allowing the carriage F to travel forward under the action ofthe drum W. As explained above the carriage F is fed on by the rockingof the rack S and when the line of type has been set the rods q 11* aredepressed by actuating the printing lever O. The rods 9 Q) are providedwith toothed sleeves loosely mounted thereon which are actuated byprojections Q2 Q3 respectively formed on the rods 9, 9*. On the rods 9,9 being depressed the projection g on the rod 9 will engage with thesleeve q (Fig. 5) and thereby rotate the drum V in a counterclockwisedirection owing to the teeth on said sleeve engaging with the pinion wsecured to said drum. The rot-ation of the drum W will cause the band Uto move in the corresponding direction and return the carriage F toits'initial position. This movement of the band U will also r0- tate thedrum V and in so doing will cause the sleeve g on the rod 9* to descendowing to the rotation of the pinion to which engages with the teeth onthe said sleeve. The drum W is provided with a torsion spring which onthe upward movement of the rod is wound up so as to be ready to actuatethe carriage in the opposite direction during the subsequent operationof the machine. The movement of the traveling carriage one step onwardcauses the pins 7' to come under the next quadrant so that a fresh stopis raised and a fresh type wheel operated; as each key is pressed theseries of type wheels or some of them are operated in sequence until theline of type or characters is complete. In order that when a type wheelis brought to rest by its stop it shall come to rest quickly andsilently, the stops are formed as a split pin or equivalent frictionaldevice so that the projections J J are gradually brought to rest betweenthe two portions of the stop. The positions of the parts of the devicemay be reversed,

2'. e. the split portion may be on the type wheel and the unsplitportion formed by the stop. Assuming now that a line has been completedit is necessary to space the type wheels according to requirements andthis is effected by means of the springs a Fig. 10, disposed betweeneach disk a. The last few of the series of disks have three holes a inthem, as shown in Fig. 1O adapted to receive three corresponding pins (4Thus if any of the wheels have not been operated, they may slide freelyfrom left to right as required, presenting a blank at the printingpoint. The last wheel operated however occupies a position in which theholes in the disk (6 do not register with the pins a and the lateralmovement of the wheels is arrested at that particular wheel or disk,thereby insuring an even margin. The spacing is effected by thehiovement of the printing lever O which upon being depressed carries therod g with it, the cam Q'XX causing the roller 92X on the springcontrolled lever to relatively ride upward and thence inward on theincline; the rod g thereupon withdraws and allows the last wheel or diskto slide along the rods a and shaft 13. The printing operation takesplace by pressing the lever O downward, this action first of all causesa knife-like or bladed device to descend on to the type wheels intogrooves provided therein for the purpose, lightly engaging them so as tomaintain the wheels in their correct position for printing. Referring toFigs. 1, 7, 8 and 8 this is effected by a knife X, which comes betweenthe type characters before and during printing and is instantly releasedat the beginning of the upward movement. This action is effected asfollows Mounted between the plat-en supports (Figs. 1, 7 and 8) is aspring controlled knife X. One of the arms 2* carrying the knife isextended into a pawl 3 (Fig. 8 On the frame Q a projection is arranged.Upon the downstroke (of the rod 9) the pawl 3 slips over the projectiona (see Figs. 1 and 8) and the knife readily alines the type wheels byengaging in the notches formed on their peripheries, but on thecommencement of the upstroke the tail pawl 8 which is now beneath theprojection 4 is held down, which has the immediate effect of throwingthe knife X upward and leaving the wheels free for the collecting frame.Before the completion of the upstroke the tail pawl 3 passes above theprojection 4. The printing roller is pulled down on to the type wheelsby means of the rod q pertaining to the frame Q, the said rod carryingthe brackets 01 whereby the roller N is supported. As soon as a line isprinted the roller N rises but in so doing it makes a rotatory movement,the space of one tooth, as shown in dotted lines in Fig. 1; the saidroller carrying at each end a ratchet device which engages with the pawl71 carried by the frame Q. In rising the ratchet device is caught by thepawl n and can only escape therefrom by rotating on its axis. As soon asthe printing is effected, it is necessary to return the type wheels totheir initial position in readiness for printing a fresh line, to besubsequently completed as hereinbefo-re described.

It is obvious that after a line has been set readyfor printing theprojections J pertaining to each wheel will be in various positionsabout the latter, a collector Y is therefore provided having a smallpinion Z at one end, see Fig. 1. WVhen the printing lever O is depressedthe rack 0 causes the said pinion to rotate idly owing to the action ofthe snail cam Y, Fig. 15, and pawl Y, but when the lever O returns toits normal position, the pinion Z is locked in such a manner that itcauses the collector Y to rotate around its axis in the direction of thearrow, Fig. 1. The front part of the collector is provided with a comblike device Z Fig. 14 the teeth of which consist pref erably of a numberof split pins constructed in the manner shown in said figure, or in theform of bent or waved spring metal 2 The operation of the collector isas follows r-When a line has been printed by the depression of the leverO the collecting device is actuated on the return movement of saidlever. At the beginning of its rotation the collecting device Y drops tothe bottom of the snail cam Y under the influence of the spring Y (Fig.10) and as it rotates its outer bevel y comes against a lever y (Fig.1). This has on its spindle the catching lever 3 and the comb device Twhich may consist of a number of teeth similar to those described inconnection with the collector. When the end 3/ of the collector comesagainst the lever y the horizontal arm g is lowered and catches underthe hook g of the pawl S thus holding down the comb device T In thecourse of the rotation of the collector the comb like device Z (whichwhen at rest is clear of the pins J engages with the pins J and carriesthe type wheels round, the pins wedging themselves between the adjacentfaces of the split pins whereby they are held or where the teeth are inthe form of the bent or waved spring metal Z engaging with the face ofsuch teeth and coming to rest in the recess provided by the waved formof the teeth. Toward the end of the upstroke the sides Y" of thecollector Y are expanded by means of the cam Y and in expanding releasethe pins J which are caught by the comb device T which has been broughtinto position to receive them in the manner already described. When allthe wheels are set to zero, or their normal position, and when thecatches L and the comb device T are holding the wheels, a projection gon the lever O comes under a horizontal arm 3 of the pawl S giving it anupward push, sufficient to release the hook y from the horizontal arm yThis causes the comb device T to spring to the position shown on thedrawings when the pins on the wheels can pass by, to their various setpositions. The first downward. movement of the rod 9 depresses the arm Vwhich is normally kept in position by the spring V thus freeing the armW, which carries the fiat spring V between which and the arm V the bladeTV is wedged. Until the arm V is depressed the collecting frame Y cannotrotate.

The projecting stops 9 are returned to their original position by meansof the grid device Z (Fig. 9) through which the stops pass and in whichthey can move freely. The stops are operated by this grid, when movingdownward by the lower shoulders 9 shown on the stops in Fig. 1. Thisgrid is provided with a rod Z which is fixed to it. The rod Z is free tomove up and down in the socket Z (Fig. 18). Pivoted to the rod 9 is anarm (1 the forked end Q4 of which engages with a projection Z on the rodZ. On the downward movement of the rod 9 the arm 9' and the grid deviceZ move downward in one piece until the arm Q3 passes the projection Z(Fig. 13) mounted on the frame Q (Fig. 1). On the arm passing the saidprojection Z the perpendicular part of the arm g swings outward and thedownward movement of the grid Z ceases. This allows the rod 9 to furtherdescend so as to allow the necessary length of stroke to be given to theother movements which require it, while the grid having done its worksremains stationary. On the upward movement of the rod 9 the spring 9pulls the arm Q3 into the perpendicular again thus preventing it fromfouling the projection Z.

The change key mechanism is shown in Figs. 1 and 11, and consists of akey 2, rod 3*, twisted arms or blades 4P and 5 twisted rocking dogs orblades 6* and 7, spring 8 and pawl 9. In utilizing the change mechanismit will be remembered that the type wheel instead of falling in thedirection of the arrow is caused to rotate in the other direction by ajerk or kick being imparted thereto. In the normal position of thechange key 2, the arm 4 is in contact with the rocking dog 7 therebykeeping the arm 5 out of contact with the rocking dog 6*. Upon.depressing the key 2 however the rocking dog 6 is brought into contactwith the arm 5 by the influence of the spring 8. If while the change keyis depressed any one of the ordinary operating keys is struck,

the rod R to which the arm 5* is attached will be rotated and willengage with the rocking dog 6 thereby imparting motion to the squareshaft 10 causing the pawl 9 to move forward under the stop J The pawl 9by kicking against J X causes the wheel A to rotate in the oppositedirection when it is arrested by the stops as before described. Thenecessary kicking motion is obtained by the contact of the arm 5*, withthe rocking dog 6 which is so bent that the arm 5* is suddenly releasedfrom contact when the arm is at its limit of motion.

The traveling carriage F (Figs. 6 and 6) has connected thereto a secondmovable frame 0 provided With racked guide rods 0. These rods slide inguides cl fixed to the carriage: mounted between the guide plates arepinions e on a common spindle 7 which at one end is bent at right anglesand provided with a button to form a shift key 9. The frame Z) carriesfor each of the split setting pins f/ an upright hooked arm is. Now whena line of type has been set and a mistake is observed, it is onlynecessary to bring the traveling carriage back to the position of theerror and depress the key g. This action draws down the frame Z) (bymeans of the pinions e and racked rods 0) bringing with it a row ofhooked upright arms in, one for every split pin 9 in the row. It istherefore assured that the pin 9 raised in error (whichever one it maybe) is set back to its normal position and the tripping pawl m (Fig. 4)where it is shown in the lower position, rises with the frame 6 and itstail a engaged with the top ledge of the transverse bar 0 (Fig. 4:)causing the nose of the pawl to come into engagement with one of thenotches 39 formed in the freed wheel A and give said wheel a kicksending it back to its zero or unset position where it engages with thecomb like device T Fig. 1, which has been previously depressed by handto receive the projection J on the wheel. On the wheel being releasedfrom the comb like device it can be set by de pressing the right key (aor 0, e or 6) into the required position bringing the correct unit: oftype on to the type line to replace the discovered incorrect one.

It will be understood that the pawl 9 moves with the traveling carriageF and comes to rest under each of the projections J as the carriagemoves forward.

In order to obtain clear printing the inkingor carbon ribbon X (Fig. 12)is arranged in such a position that a new surface is presented to eachtype character, and for this purpose the inking or carbon ribbon travelsin a transverse direction, 2'. e. a direction not parallel with thedirection of the printing line.

All the movements are more or less silent and the individual hammeringof the type on the platen roller incidental to typewriters as ordinarilyconstructed and worked is entirely dispensed with.

Although in the above description the invention is referred to asapplied to a typewriting machine, it will be readily apparent that, bymodifications which will in no way change the nature of the invention itcan be employed with other apparatus so as to produce matrices in flong,plastic or semi plastic material from which castings may be obtained inmetal, or other effects obtained for the purpose of reproduction, suchas stencils perforated paper or other devices well known in the art.

The invention may also be employed in connection with electric telegraphand similar appliances, the keys being depressed by electrical meanssuch as magnets or the like.
